"the parts and combinations thereof herein set forth anu claimed.

Among Ithe objects and advantages of the invention are they saving oi time and labor in cutting and handling the grain preparatory to threshing; the better drying and curing oi the grain in loose form as distinguished from bound form; the saving or" the expense .incident to the binding system in cluding cost ci machinery and breakage or iailure in operation oic the same, with conscouent loss or' valuable time in the limited harvesting season; repairs `oit binding ma.- chinery; the cost ot binding twine; the loss ci grain rattled out from the grain heads by such machinery and in handling the bundles after binding; the further saving oi' labor and time in gathering up widely sca tercd hundlesor small shocks, .and also of time with respect to the occupation of the land by widely distributed harvested grain which delays the preparation of the rand for the next erop; and, in general, the substitution for all of these operations of niaci'iincry Vwhich is relatively simple and fxpensive, requiring few and simple res, and which is nevertheless elicient in ation in place ot the more complicated L expensive machinery heretofore in genral use.A ln addition to these consideraons is the material improvementV in the 'i berries.v in weight. `rade and value, ch is of the greatest importance.

TWith such objects in view, as well as other advantages which may be incident to the use ci the improvements, the invention consists in the parts and combinations thereo hereinafter set Jrorth and claimed, with the understanding' that` the several necessary elements constituting the same be varied in proportions and arrangement without departing *from the nature and scope oi2 the invention.

Fig. 2O is a plan view showing a modification illustrating a laterallyv adjustable draft appliance which may be Yapplied to Y the machine.

Referring to the drawings, which are typical and more or less conventional in character, the mechanism illustrated coinpri'ses vpneumatic V-ineans 'A for bending the grain ,'lhe'standing grain or grass is bent toward the front of the harvesting platform by an air blastfrom La casing 12 (Fig. 12) and fan 13 therein, the shaft 14 of which is journaled in a frame 15 upstaiiding from the iframe 1. This casing is adjustable to direct the blast by-a link 16, arma 17, and

shaft 13 mounted o n the frame l5 and having a hand lever 19 (Fig. 1) in reach of the drivers seat 20'. The delivery end of the casing 12 can be adjusted to the exact height desiredyaccording to the length and condition of the grain, by the said lever, and will Y be so held by afriction screw 20 which bears on the sha-ft 13. 'This pneumatic device lias important' advantages over the usual reel, in that it is not so subject tofbrealiage and can be adjusted to operate properly on the shortest grain, the blast Vbeing then dirccted Vto strike just above 'the cutter', and it does not shake out and'cause fthe loss of grain berries as does a reel.

'A draftmeans is kfurnished by a 'tongue 21 ig.6) coiiii'ectedwith the bottom frame elements-of the machine, or a gasoline tractor may be used. The cut grain is received apron 22 mounted on rollers 23,124 having their shafts -iournaled in a frame 25 supported in the frame l (Fig. 4). The inner roller 23 and the apron are actuated by a s proclret`26, chain 27, and sprocket 23 on the shaft 5. The inner end of the apron 22 delivers the grain in the open throat of an Viii oasings 32, 33 and delivering air blasts to the trunk 29 bypassages 34,35. These fans` are driven by pulleys 36, 37 and beltsl guide 52. `at 54 and having at its rear `end a shoulder or hook 55 which is adapted to be engaged 1 "foriner.

The grain is ele!" vthe air delivery of the casing 34, so that the grain straws can be properly acted on by said air as they are being delivered by the-aproinand-the lower part of the air trunlr 29 is so arranged that the frame 25 may be tilted as'liereinafterdescribed. The truiilhasa distributer42` (Figs. 7,13, 14) directed" to deliverfthe yelevated grain into the stack former device 1), which is` provided vwith 'cheek lplates 43v Apivoted to the sides ofthe' distributor Vat44. vlhese cheek plates'are connectedffby `alongitudinal `har `45 pivoted to thematfll, lso as to be swingable together to distribj'u'tey tlieloose grain "to thevir'iiddle,I front-and rear of the stack former as -niay be 'required `for the proper bu'ildiiigof the stack, being pulled forward by -acord 46 and returned by-a spiing'47.

The cord may be piilledby the driver at tached toa slide/51 r'eoipi'ocable Yin a fixed 53 is an arm pivoted to thelslide byfa pin 56 (Fig'll) carried by an adjustable member or hood 57. This hood 'can-bel clamped at any 4desiied point `on the `circumference of vtliewheel 58 by `a. set screw 59. The rotation of this wheel carries `thepin 56 periodically into engagement Awith the shoulder 55, soasto draw the arni 53 rearwardly and swing the `distributer elements 43 towards Vthe front `of the Vinachiiiesothat the grain -willbe delivered vin the forward Yfpart of the `stack former.

As the'lpiii 56 rotates rearward lit carries the rear vend of the arm 53 into contact with the topvof a lpin 59 (Fig. 5) so that the arm is arrested andldiscngaged from the pin 56, whereupon 'the spring 47 will instantly swing the said distributer elements reary `ward and draw the arm 53 `back to its for on a laterally traveling endless platform" Several such pins 56, properly spaced apart,

may be attached to the wheel 58 to increase the frequency of theloperation ofthe dis tributer devices aiidobtain thedesired distribution of the'grain endwise of the stack The-extent of thenioveineiit of the distributer can be regulated by adjusting thepin 59'so as-to vary the tiinefof the disl engagement of the arm-53, which is accoin plished byinouiiting thel pin v59 on a. slotted arm 60 and by clamping said arm to a suit able portion of the frame in the desired position, -thc arm being secured after adto take neck Weight from the team and to hold up the front oi the machine whenfit is not in use, and which are or may be mounted as caster Wheels under the front part .of the frame 90.

T he harvester frame 25 is mounted on a transverse axis in the traine 1, so that the Acutter can be run close to the ground in the case of short grain, or can be elevated to eut the grain at a high level and save the expense of handling' and threshingfan unnecessary `amount of straitY Where the grain is tall. By its adjustment l `can cut close tothe ground when the grain is relatively ripe and dry so as to getthe necessary `l'ezfigth of straw and amount olf sap tor the increase and.maturing` of the grain berries While sweating in the stack; or can cut at a liigher level to incluce a lesser length of the straws and less sap and moisture in the 'stach when the grain is rless ripe, thereby avoiding undue sweating;` l of the Vberries while they `are inK the stack. rThe raineQ can be so adjusted without affecting the frames 1 and 00 or the draft frame 21 or .other parts of the machine. 'lhe traine' 1 is 'provided With a limitingslot or guide 91 (Fig. 6) for the shaft ot the drivingl roller 23, and with aslot through Which Worlrs the pitinan A.hand also with guiding brackets 96 for the inner end member et the piyoted iframe rThis axis may be arranged near the rear side oi' the platiornrframe 25 or at any preferred distance therefrom. is shown it is at about the vmiddle oi said frame, the inner journal for said axis being formed `by the end 01"' the bull Wheel axle 92 and the outer journal being,- formed by 'fa stud .shaft "97 fixed or turning vin the frame 1. The trame 25 is tilted as desir d toradjusting the height of the eut-ter by a forwardly extending lever 97 attached to its inner end.

The entire base of the machine. comprising the frames 1 and 007 being' one rigid structure and carried substantially by only two'ground bearings on wheels 2 and 91, and Ythe grain Wheel bei'w omitted, there is substantially no or relatively little side dra'l't, and the draft` trame or tongue 21 is made rigid'with said base by braces 21 and -is arranged preterahly between said Wheels 2 and 01 and near the line of the bull Wheel 3, or at such point to practically eliminate side draft. 98 is an emergency Wheel mounted at the grain side otl the machine on the frame 1 and conveniently on the stud shatt 9T. This wheel is held normally out of con tact With the ground and serres to reduce friction and side dratt in ease the grain side of the machine should encounter a mound or high bit oi`groand.1 but at other times it does not bear on the ground and normally carries no Weight and causes no side draft` The stach former traine comprises upright fat- 117 to thestaclrtormer trame.

posts 99, one atreaeh eornerl'oi `the threesidedbase sframe f90 (Fig. "6) the latter being open at the rear furthe discharge oi.: the stack. Attached to theorward.posts is a front Wall `100,-and side Walls 101 and connected bywhinges 102 with the rear yposts so that they maybe swung outward slightly at theiriront ends to release the staelrvtor its discharge. These three -LWalls may be of boards7 sheet metal or lattice Work, adaptedto contain the frontandfsideslot the stack of grain as iit is 'built up.

The side Walls-are` swung outward for a limited distance :by 'linlrsl103 4arra.nf ged outside oi" the 'frontwafll'100 and pivotally conA nected at 1011 AWith braekets'10 which are bolted to thefinnersides ofthe :trontends of the Walls 101 (Figl).

The pivots 1011 inthe .brackets 105 passy tronithe inside tto the Voutsiderot the-stack former through aslott 1065in the front wall. This slotis formediby anglebars 107V `which are bolted'to'thev posts`299. TheA- side Walls are further, controlled-and guided Yand held from distortionby theoveight of thestaelr by trames 10S which areboltedito'the side u'allsat 109 andcarryat their inner ends forward projections'Whiehswork .in the slot 10G. rlhese projections are .preferably formed by rollers .110 litting lin the slot(` Washers 111 A which engage the inner and outer faces ot the angle bars, andb'olts 112 which pass throughsaid Washerszand rollers and through the :inner ends ol the trames V108. The pivots 1011 may have similar rol lers and Washers 111. vThe links 10i-3 are piroted at 118 to thelupperfand lower arms of a lever lllpivotedat 103v and the upper arin'oin` said lever is connected by a bar with aliand lever 116 which is pivoted The bar 115 passes through a fixed guide 118, and is Y forined'with notches 119 ywhich may engage the lower partv otsaidguide'so as to hold the side .walls `101 in their inner or outer positions. The pivoted partei thedever 11G` is formed With a slot 120 lwhich enables the operator to slide the lever up and down a little to engage or disengage'the bar 115 with or from the saidguide. Before the torniation of a sta'clr the'lever 110 is so operated as to draw the forward ends ot the side walls 101 inward until they are nearer to gether than are the rearlends, and the interior of the Vstack former `flares rearwardly. li'slhen said forward ends are released and the stack deposited' the side Walls and parte of the lstack former become, or may be, further and further-away from the sides ot' the stach as the machine moves forward from the stack so as to depositthe stack iu peu lect form asfpossible :and -without undue friction.

The rear oi' the `stack former is closed Whilev a `stack is being formed by an 11p-130 wardly and rearwardly swingable gate 12-1 which is hung at points below its top by pivots 122 (Fig.v 9), 'so that the gate is partly or nearly balanced, said pivots being carried in swingable arms 123 which are pivoted at 124 to the rear posts 99. Ropes 125 attached to the upper ends of the arms 123 lead under sheaves 126 and forward to points of attachment atl 127 to reciprocable rods 128, one at each side of the stack former. These rods are guided in slotted brackets 129 attached to bars 130, the latter being fixed to the posts 99 (Figs. 3 and S). rf'liese rods are attached at their front ends toa yoke 131 pivotally mounted in bearings 132 attached to the 'front posts 99, are held rearward by spring 132', and

are reciprocated to swing the gate 121 first bodilyvreaiavard and then up-ward, by an arm 133 attached to an upper cross bar of said yoke. This arm is operated by a link 134, arm 135, rock shaft 136, arm 137, link 133 and hand lever 139 near the seat 20. The lever 139 is guided in a slotted bracket 136 attached to a front corner post 99 and has a pivoted spring latch 137 adapted to engage projections 13S and 139 on said bracket.` (Figs. 1, 2, 8 and 10.) Arms 140 pivoted at 141 to the rear posts 99 serve to hold the gate 121 from opening during the forming of a stack, and also to close the gate, and said arms are swung rearward to release the gate by the said rods 128 which are pivoted to the outer ends of the arms at 142 (Figs, 3 and 9). This upward swinging of the gate removes it out of the way of the bottom elements olf the stack former as they are subsequently moved rearward. Then the stack is discharged it pushes the end gate further rearward onits pivots 122, and the gate trails lightly on the top of the stack as the team moves forward, the gate being' nearly'balanced on its ypivots 122, and is subsequently closed by a reverse movement of the parts above described, and is held closed for the building of another stack by the arms 140.

The rear part of the bottom of the stack former is composed of longitudinal rods 143 (Figs. 3 and 8) having eyes which embrace the axle 92, which rods are spaced apart thereon by loose sleeves 144, the rods be ing adapted to swing vertically. The forward part of the bottom is preferably composed of rods 145 which are fixed in short upstanding brackets 146, these brackets being attached t-o a movable frame 147, this frame being adapted to slide backwards and forward and to tilt on the endmost sleeves 144. The rear parts of theY rods 145 are flexible so as to yield downwards to accommodate the discharging of the stack. The downward movement of the rods 143 is limited by a transverse member 148 of the frame 147, andthey are lifted bythis member when the frame tilts downward and forward. The rearward sliding of the frame is limited by a downwardly extending shoulder or stop 149 which is attached to its under side and is adapted to engage with the front part of the axle 92 or with the parts 143 or 144 mounted thereon. rlhe said frame has pivotally connected therewith at 149 a forwardly extending arm 150 which extends through a slot 151 (Fig. 1) in the front wall 190 and serves to guide the frame in its return to its forward stack supporting position. 152 is a space former adapted to produce a ventilating air space in the base of the stack, and preferably formed of sheet metal bent into inverted U-form and suitably attached to the frame 147. rlhe lower rear corner of this space former is beveled ott as indicated at 153 so that it will withdraw readily from the stack and will not be bent out of shape by Contact with the ground. The frame 147 is provided on its under side with inclined runners 154 which work on top of two of the sleeves 144 on the axle 92. The forwa rd end of the fra-me is normally heavy enough to fall by gravity after the discharge of the stack, and the inclination of the runners is such that the frame will then slide forward to its normal position. l can employ also a` spring 155 attached to the front end of the frame and to the frame 90 which will aid the forward return of the frame 147 in case the whole stacker should be inclined backwards by the formation of the ground. The said bottom frame is reawardly tilted for the discharge of the stack by a rope 156 which is attached to the front end of the frame and runs over a sheave 157 to a drum 153, on which it may be wound up by the operators turning a crank wheel 159 which is connected by a shaft 160 with the said drum.

161 is a rock shaft mounted at the front of the frame 90 and operable by a foot lever 162 to secure or release the frame 147 (Fig. 5). This rock sha-ft is connected by an arm 161 and a link 162l with a pivoted and swinging dog 163 which is adapted to hook over the front bar of said frame to hold it from rearward sliding. 164 is a sliding spring bolt which is adapted to extend over or be withdrawn from the said frame to hold it down'or to permit it to tilt upward, and this bolt is connected by a link 165 with an arm 166 on the rock shaft 161.

The trunk 29 is made strong and stift, especially by stout front and rear end boards 167, and is one of the weight sustaining frame elements of the machine. .ltis preferably arranged near the bull wheel and its upper end at said boards'167 is connected by front and rear inclined angle iron frame elements 163 (Fig. 19) with the outer endof the harvesterbaseframe 1,and this llO connection'may bethrough the'niedidm ofi the frame 15 (Figa 19),. At' thev stackfor mer side of said trunkfitsfupper end, preterablyv at the same points o1 attachnfientV tothe end boards 167, is connected with the base trame out the stack former by front and rear inclined angle iron lira'me'elements 169 (Fig. 1); At a suilicientdistance above the base trame, horizontal frame elements 170, 171 (Fig. 19), Vat the trent` and rear otl the trunk; connect it with the member 168`andframe 15, andfwiththe member 169, respectively. V172 is an angleiron inclined trame member connecting the-upper part ot the tru`nk'29 with the` outer part of the trent of the-stack former frame. The iveighto't the machine is thus largely concentrated on the bull Wheel.

It- Will? be understood that the throat at the lower end of the airpassage 34 and at thelower end of the trunk 29, Where the air blast takes hold ofv the grain on the inner end ot' the apron 22,'may be modiied-as required for the best action of said air blast for the purpose. of propelling the graininto and-up the said trunk, and the showing in the drawings is to be considered as diagrammatic in this respect.` rEhe Wor'd grain as used herein is intended to include hay, straws and other crops adapted tobe harvested by my machine.

In combination With the said frame and two-Wheeledsupport' (Fig. 19)- for' the harvesting, grain-carrying and grain stacking elements, av` modification ot the dla't `de 'rice may be l'enuoloyed (Fig.v 20). In this construction thelcenterror line o-application ol" thedrat-may befShi-ted--laterally at will, according 4to the average Weightv o-thesta'c. 1 oraccording tothe varying Weight of the' same, or as maybe required` by the thickn'essland resistance' voli-the grain, orby the' softness of the ground which may atiiectfthe Wheels Q'andDl differently. 173 is `afbase frame vmember Which-may be-a'ttached to the trames 1 andDO or may take the place of the front members' thereof. 174 isa channel ba'r to which is attached the tongue 21 and braces 21( or other draft connection; 175 indicates rollers 'engagingini the channelo the bar 1-7fl'tofhold the same to the membcr 173 andv guide it infitsvlateral. adjustment.
